The symbol shows the location of the Waltham (Leicestershire, England) transmitter which serves 770,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Waltham (Leicestershire, England) mast?

jb38: Mine was recording Film4 (COM6) when it went off. It continued recording a blank screen.

Prior to going blank the picture went upwards once or twice, just as in the days of analogue without a vertical hold - for that reason I first suspected that the tuner had gone.

brian: I have a sneaking suspicion that a few others who have also experienced this problem might well be trying out your procedure for themselves albeit with the qualification of nothing being guaranteed, but though so long as they remember NOT to use the channels numbers you have mentioned (Ch29 / Ch56) but the COM4/ SDN then COM5/ArqA channel numbers used by the station they receive from.

Dave Lindsay: Yes, and can fully understand the reason for you having suspected that your tuner had packed in, because if it had the symptoms would have been exactly the same.

I have to say though, that when I first seen these problems being mentioned this morning I wondered what your own findings would be, as I had only noticed late yesterday evening that you had previously made a posting commenting on a suspected EPG problem you were experiencing, and had typed out a short reply (not in the reply box as I copy and paste into it) along the lines that I felt the problem was more likely to be caused by a software glitch within the actual box rather than the data sent out by the transmitters involved.

However after having seen the sheer numbers of people complaining I decided to scrub what I had previously typed out as it wouldn't really have added to that already known.

jb38: My Sony is recording at present so I might have a go tomorrow and see if tuning in the PSB channels only makes a difference.

If you are referring to the issue I had with timer recordings set for LCN001 (BBC One) where the EPG Link was on and where, seemingly, at random intervals it decided to record from one of the BBC Ones in my 800s instead then I don't think this has anything to do with the current widespread issue:

Emley Moor (Kirklees, England) Full Freeview transmitter | ukfree.tv - 11 years of independent, free digital TV advice

We also have a Pioneer DVR-440HX and the colour scheme of its EPG has also changed, along with the now and next box and the information box which gives the blurb for the current or next programme.

The issue only appears when COM5 is tuned.

I tried running Easy Setup (having set the country back to UK), doing the unplug aerial trick so as to store only PSB2 on C44 (Emley Moor). The EPG worked fine and the broadcast pictures were available (no black screen). I then added PSB1, COM4, COM6 and then COM5 at which point it gave up. Prior to adding COM5 the EPG was available, complete with programme titles. Having added it the EPG has no programme titles.

So I tried again, this time picking up PSB2 only during the scan. I then added COM5 manually and it the fault showed.

Interestingly there is something with the picture when it goes wrong when that picture is black. What happens seems a bit random but the effect is something appearing momentarily (split second) on the screen such as a coloured line at the top of the screen or some other momentarily blip, blob or pixel of colour/white.

I've just done it again, storing PSB2 and then adding COM5. Having exited the menu (having added COM5) ITV displayed momentarily with the picture stopping and jumping back and forward a frame about three times, this reminding me of the pause function on VHS. The screen then went blank although the EPG screen is accessible, it having no programmes even though it did when only PSB2 was stored.


I repeat that when it failed yesterday evening it was recording from COM6 and so couldn't possibly have been tuned to COM5. Why then does it appear that the fault lies with COM5?

The only possibility I can think of is that this has something to do with the fact that the same EPG data is broadcast on all muxes and that something which relates to a service on COM5 is corrupted or otherwise doesn't agree with these models.

Dave Lindsay: These tests that you have carried out somewhat backs up Brian's (located within the Waltham area's) findings insomuch that something associated with COM5 (no matter where its received from) is triggering the problem in the Sony, this being why that the Sony apparently works OK when its been set up on France, simply because no EPG containing the suspect COM5 data has been stored.

This in theory meaning that if the Sony box is set up as normal in UK followed by manually tuning in each of the muxes one at a time "with the exception of COM5" this will result in EPG listings been seen as normal minus everything associated with COM5.

In other words if the BBC mux is stored first the EPG will only indicate LCN numbers relating to all BBC programmes carried by BBCA and nothing above this (meaning numbers), the additional LCN numbers being added to as they are being picked up from each of the muxes subsequently scanned, which of course is the way that LCN numbers are stored in the first place, because if you scrub everything stored and then tune in the SDN mux the EPG listings will start from LCN 010 and with no numbers below this being seen.

Thanks for your post this has really helped me I went to record a programme last night on my Sony HXD-890 and found no channel numbers, I had purchased a 5 year warranty and was going to invoke it but I have followed your procedure and mine is working fine now, I hope Sony send out a patch/fix for this as I suspect many others in the Waltham area are in the same situation.

Until the next Update, that is, because there is apparently no way of preventing this device from adding any new multiplex it finds.

It's all working again!

The EPG colours have returned to how they were on the Sony, although those on the Pioneer DVR-440HX are still the "new" cyan (although it hasn't been given a retune which I don't know whether makes any difference).
